Description

Technical Field

[0001] This utility model relates to the field of agricultural fertilization technology, and in particular to an agricultural fertilizer application device. Background Technology

[0002] Agricultural fertilizer application equipment, as a key tool in modern agricultural production, is widely used in the planting process of various crops. Its core function is to apply fertilizers to the soil precisely and efficiently to meet the nutrient requirements of crop growth.

[0003] Patent CN222736619U discloses a corn planting and fertilization device. In use, the device is moved by a pusher, causing a soil-breaking plate to break the soil layer. The rotating wheels drive the axle to rotate, and the axle transmits power to a rotating rod via pulleys and belts, causing the rotating rod to rotate synchronously. A cam on the rotating rod rotates with the rotating rod. When the cam's protrusion contacts the lifting plate, it pushes the lifting plate upwards, which in turn drives the cross support frame to slide upwards along the guide plate, compressing the spring. At this time, the second discharge pipe at the bottom of the fertilizer hopper is blocked by the bottom of the L-shaped plate. When the cam's protrusion leaves the lifting plate, under the spring's elastic force, the support frame drives the fertilizer hopper downwards, which in turn drives the bottom of the second discharge pipe away from the bottom of the L-shaped plate, allowing sowing and fertilization to proceed through the second discharge pipe. This cycle repeats, thus completing the corn fertilization process. However, the above-mentioned device has the following defects when in use: the fertilization mechanism of the device directly puts the fertilizer onto the soil surface through the discharge pipe without setting up a special burial structure. After the fertilizer is put in, there is a lack of effective covering measures, which further aggravates the problem of nutrient volatilization and loss.

[0004] Therefore, how to prevent fertilizer from volatilizing and being lost due to exposure after application has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0005] The present invention aims to provide a fertilizer application device for agricultural fertilizers to overcome the shortcomings mentioned above.

[0009] The trenching component is located at the front end of the vehicle frame and is on the same horizontal line as the outlet of the discharge hopper.

[0010] A support rod, the lower end of which is connected to a soil-covering plate, wherein the soil-covering plate and the trenching component are located on the same horizontal line; and

[0011] A fixing component is located at the rear end of the frame and is detachably connected to the support rod.

[0012] Furthermore, the fixing component includes a fixing sleeve and a fastener. The fixing sleeve is fixedly connected to the side wall of the rear end of the frame, the fixing sleeve is slidably connected to the support rod, and one end of the fastener is threaded through the side wall of the fixing sleeve and selectively abuts against the side wall of the support rod.

One end of the rotating rod is provided with a threaded section, which is located at one end of the spreading block and is threadedly connected to the first nut. The other end of the rotating rod is drivenly connected to the output shaft of the first motor through a coupling. The frame and the first motor are detachably connected. The spreading block has at least one receiving groove arranged around its circumference, which is located below the discharge port of the fertilizer hopper.

[0015] Furthermore, the discharge port of the fertilizer hopper has a circular cross-section, the upper end of the mounting box is provided with a connecting ring, and the side wall of the discharge port of the fertilizer hopper is provided with a first ear plate. The lower end of the connecting ring and the mounting box are both provided with a second ear plate. The first ear plate and the second ear plate of the connecting ring are detachably connected by a first bolt and a second nut. The second ear plate at the lower end of the mounting box is detachably connected to the frame by a second bolt.

[0016] Furthermore, the vehicle frame is provided with a placement slot for placing a battery, which is electrically connected to the first motor.

Both of the switches control the first motor and the drive motor through the controller, and the adjustment knobs control the speed of the drive motor through the controller.

[0020] Compared with existing technologies, this invention has at least the following advantages: During use, the moving frame propels all components across the field. Fertilizer stored in the fertilizer hopper is conveyed downwards, first passing through a spreading component located between the fertilizer hopper and the discharge hopper. This spreading component can adjust the spacing of the fertilizer application according to actual fertilization needs, ensuring the fertilizer enters the discharge hopper below at preset intervals. Simultaneously, the trenching component at the front of the frame operates concurrently, pre-drilling trenches in the soil to prepare for fertilizer application. Once the fertilizer falls into the trenches prepared by the trenching component through the discharge hopper, a covering plate positioned at the same level as the trenching component immediately follows, pushing the soil from both sides of the trench back into the trench, thus promptly covering the fertilizer. This process effectively prevents fertilizer from evaporating and being lost due to exposure to high temperatures and other factors, thereby improving fertilizer utilization.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] Reference Figure 1-3 This utility model provides an agricultural fertilizer application device, including a movable frame 1, with a fertilizer hopper 2 connected to its upper end. The inner wall of the fertilizer hopper 2 is provided with scale lines. A discharge hopper 3 corresponding to the fertilizer hopper 2 is provided at the lower end of the frame 1. A spreading component is arranged on the frame 1, located between the fertilizer hopper 2 and the discharge hopper 3. The spreading component is used to adjust the spacing of fertilizer spreading. The fertilizer falls from the fertilizer hopper 2, is processed by the spreading component, and is discharged from the discharge hopper 3. A furrowing component 4 is arranged at the front end of the frame 1, and the furrowing component 4 is on the same horizontal line as the outlet of the discharge hopper 3. The lower end of the support rod 5 is connected to the soil covering plate 6, and the soil covering plate 6 is on the same horizontal line as the furrowing component 4. A fixing component is installed at the rear end of the frame 1, and the fixing component and the support rod 5 are detachably connected.

[0030] Reference Figure 1 The fixing component includes a fixing sleeve 7 and a fastener 8. The fixing sleeve 7 is fixedly connected to the side wall of the rear end of the frame 1. The fixing sleeve 7 is slidably connected to the support rod 5. One end of the fastener 8 is threaded through the side wall of the fixing sleeve 7 and selectively abuts against the side wall of the support rod 5. The fastener 8 is a knob bolt.

[0031] By tightening or loosening the fasteners 8, the position of the support rod 5 within the fixed sleeve 7 can be adjusted, thereby changing the height of the soil covering 6 and preventing the soil covering 6 from rubbing against the ground during transportation.

[0032] An installation plate 9 is fixedly connected between the support rod 5 and the soil covering plate 6. Two guide plates 10 are fixedly connected at the lower end of the installation plate 9 at an incline. The two guide plates 10 are symmetrically arranged at both ends of the soil covering plate 6, and both ends of the soil covering plate 6 are fixedly connected to the two guide plates 10 respectively.

[0033] Reference Figure 3-4 The spreading assembly includes a mounting box 11, a rotating rod 12, a first motor 13, a spreading block 14, a receiving groove 15, and a first nut 16. The mounting box 11 has openings at both the top and bottom, and these openings are detachably connected to the lower end of the fertilizer hopper 2 and the frame 1, respectively. The rotating rod 12 rotates horizontally through the mounting box 11. The limiting protrusion of the rotating rod 12 is detachably inserted into the limiting groove of the spreading block 14. The spreading block 14 is rotatably positioned within the mounting box 11. One end of the rotating rod 12 extends into the mounting box 11. One end of the rotating rod 12 has a threaded section located at one end of the spreading block 14. The threaded section is threadedly connected to the first nut 16, which is a reverse-threaded nut. The other end of the rotating rod 12 is connected to the output shaft of the first motor 13 via a coupling. The frame 1 and the first motor 13 are detachably connected by fixing bolts. The spreading block 14 has at least one receiving groove 15 arranged around its circumference, located below the discharge port of the fertilizer hopper 2.

[0034] When the first motor 13 drives the rotating rod 12 to rotate, the spreading block 14 rotates accordingly, and the receiving trough 15 receives the fertilizer falling from the fertilizer hopper 2 and spreads it out.

[0035] Since different crops have different fertilization intervals and densities, such as eggplant and corn need to be fertilized according to the planting interval, while grapes and wheat need to be fertilized intensively in the furrows, the staff can meet different fertilization needs by changing the spreading blocks 14 of the receiving grooves 15 with different spacing. Specifically, the staff can take out the spreading block 14 by pulling one end of the spreading block 14 that extends out of the mounting box 11.

[0036] Reference Figure 3 The discharge port of the fertilizer hopper 2 has a circular cross-section. The upper end of the mounting box 11 is provided with a connecting ring 17, and the side wall of the discharge port of the fertilizer hopper 2 is provided with a first ear plate 18. The lower ends of the connecting ring 17 and the mounting box 11 are both provided with second ear plates 19.

[0039] The bottom of the frame 1 is equipped with a drive motor and two sets of wheels 28. The drive motor is electrically connected to the battery and provides power to one set of wheels 28.

[0040] The side wall of the frame 1 is provided with a push handle 29. The push handle 29 is provided with two switches 30 and an adjustment knob 31. Both switches 30 control the first motor 13 and the drive motor through the controller. The adjustment knob 31 controls the speed of the drive motor through the controller. The battery, controller and drive motor are not shown in the figure.

[0041] The working principle of this utility model is as follows: When in use, the worker puts the fertilizer into the fertilizer hopper 2, starts the drive motor through one of the switches 30, and pushes the frame 1 with the help of the pusher 29. At the same time, the trenching component 4 opens a trench. When the discharge hopper 3 moves above the trench opened by the trenching component 4, the first motor 13 is started through another switch 30. The first motor 13 drives the spreading block 14 to rotate and spread the fertilizer. The fertilizer falls from the discharge hopper 3 into the trench. Then the covering plate 6 covers the fertilizer. The covering plate 6 moves with the frame 1 and pushes the soil on both sides of the trench back into the trench to cover the fertilizer.
